The coffee maker is usually made of a metallic material, often made of aluminum. If steel objects can give off chrome and nickel (harmful to human health), aluminum can also cause serious damage to the human brain if it is capable of emitting from an object. Given that coffee has a slightly acidic pH, the risk increases. Therefore, if there are no alternatives to the aluminum coffee maker (without considering that even the plastic pods are not the best!) It would be advisable to take the coffee out of the coffee maker as soon as possible, since, if kept too long inside it, the The acidity of the food could easily trigger the damage mechanism, releasing aluminum particles in the drink. Important tricks should always be considered also with regard to the cleaning methods of the coffee maker:
If you really don’t want to do without using a detergent, you may still prefer a natural one. However, it would be important to avoid bicarbonate or other powerful natural whiteners, again because of the risk that aluminum particles may be released. If you still want to clean your coffee maker with a bicarbonate detergent, below is a video that explains an effective method (always in Italian) as an alternative to chemical detergents to clean your coffee pot with natural ingredients:
The advice is to carry out the cleaning practice with natural detergent only and exclusively in case of real need, since (as already reported in the initial part of the article) the coffee would go away even with the simple washing of water. The real important details not to be overlooked, therefore, are: use a coffee maker composed of material that is at least polluting (better to avoid those with paints and lead components) to wash it often entirely (and internally) with simple water and to avoid prolonged storage of liquid coffee inside it.
